Title: Improvements in yarn swifts
IPC: B65H54/58
Filed: 1938-04-13
Abstract: 495,626. Yarn swifts. AMERICAN VISCOSE CORPORATION. April 13, 1938, No. 11400. Convention date, May 28, 1937. [Class 120 (ii)] A swift for a yarn cake has a solid or tubular axle 10, Figs. and 2, of non-corrosive material such as stainless steel,and a number of resilient bands 27 secured at their ends to the axle by screws 26. The bands are arranged radially to the axle, and their curved resilient ends 25 rest against the faces of the end plates 14, 15 or rest in slots 28 in the plates. The end plate 14 is fixed to the axle through the intermediary of the collar 16, but the plate 15 and its collar 17 are removable from the axle. The removal causes the freed ends of the bands 27 to contract, as shown in Fig. 2, thus presenting a conical form suitable for the reception of a processed rayon cake. After this has been placed on the swift, the end plate 15 is pushed on, thereby expanding the bands 27 to engage the inside of the cake ; the expansion is limited by the set screw 24. The end plate 15 is held in position on the axle by the apertured plate 18 which is held by the spring 19 against the nut 22 in an inclined position across the axle to which it is thereby locked. The lock is released by pulling the free end of the plate 18 away from the end plate 15 to an extent limited by the pin 23. The parts of the bands 27 forming the periphery of the swift may have an external convex form to assist in holding them straight and rigid. The axle may be painted with acid resisting paint, and a spool 12 is provided at its centre for a weight suspension to increase tension on the yarn as it is wound off the swift. In a modification with end plates 34, 35 on an axle 39, Fig. 7, the ends 32 of the resilient bands 33 pass through slots in the end plates, and the ends of the slots engage the bands to expand them to form the cylindrical periphery when the detachable plate 35 is pushed on. The spool 12 is placed outside the swift and when the rayon cake 30 is held by the resilient bands its cloth 31 is turned over the plates 34, 35 and is held by small metal clips 29.

[Class 6(i)] In an assembly comprising a tractor towing a wheeled turn-wrest plough the wheel spacing of the plough exceeds that of the tractor, so that one wheel of the plough may run in the previous furrow, and the centre of resistance, C, of the operative plough body is laterally offset from the pivotal axis B of the bodies, which axis is arranged to coincide with the centre line of the tractor. In the form shown, the plough comprises a pair of wheels 2‹, 2‹‹ supporting a rotatable beam 5. the axis B of which is normally aligned with the plane of symmetry of the tractor 8. Offset from the beam 5 are frameworks 15 carrying the plough bodies 6‹, 6‹‹. The plough is attached to the tractor through a drag link 9 attached to an arm 10 rotatable on the beam to permit relative vertical motion between tractor and plough. Pairs of levers 16, 17 mounted on each side of the tractor and joined to the plough through slotted connections 19, 20 also permit a limited vertical movement of this nature when the land wheels are engaging the ground, but, on lifting the plough by means of a winch 21, mounted on the tractor, and cable 22, play in the connections is taken up and the whole assembly pivots upwardly about an axis E. In the modification shown in Fig. 5. the plough is provided with pair of spring-loaded coupling members 30‹. 30‹ each connected permanently to the tractor. Each plough beam carries a ring 36‹ on the end of an arm 37‹ each ring being adapted to. engage one of a pair of hooks 35‹, 35‹‹ when its respective plough body is in ground-engaging position. The Specification as open to inspection under Sect. 91 also describes a tractormounted lifting winch 38 which is connected by a cable 39 to a double-S-shaped hook 40 to the rear end of the plough. Each slackening of the cable causes a ring 42 to slide along the hook 40 so that subsequent raising of the plough effects automatic reversal of the plough bodies. This subect-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to incandescent cathodes for electric discharge tubes
IPC: H01J9/04
Filed: 1924-05-17
Abstract: 216,160. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 18, 1923, [Convention date]. Enamelling.-A wire or other body is coated with nitride of zirconium, titanium or hafnium either singly or as a mixture of two or more by heating the wire &c. in an atmosphere containing an alkaline vapour or other reducing agent, nitrogen, and one or more dissociable compounds, such as the chlorides of zirconium, titanium or hafnium. The base may be nickel, but is preferably a refractory conductor such as platinum, rhodium, molybdenum, tungsten, or an alloy. In a process of coating wire with zirconium nitride, a mixture of nitrogen and' hydrogen containing 20 to 50 per cent of nitrogen is purified by passing through a tube 2 surrounded by a vessel 3 containing liquid air, and is then passed through a heated vessel 5 containing zirconium chloride. The gases containing zirconium chloride vapour then pass through a perforated tube 7 into a vessel 8 which is heated to a temperature of 150-300‹ C., and contains the wire 12 mounted on a sealed glass stopper 9. The wire is heated by passage of a current preferably to a temperature 1800‹ C., although for coating at a lower rate a temperature of 1000‹ C. is suitable. In the vessel 8 hydrogen combines with the chloride to form hydrochloric acid which is deposited in the cooled vessel 14, and the nitride formed by the combination of nitrogen with zirconium is precipitated on the wire. Zirconium chloride collected in the vessel 14 may be used again after freeing from hydrochloric acid. The thickness of the coating may be ascertained by measuring the resistance of the wire. The coated wire may be welded to nickel and should be " aged " after inserting in a bulb. Titanium nitride may be precipitated on a wire in a similar manner from titanium tetrachloride, and heating of the vessel 8 is unnecessary. The tetrachloride is reduced by hydrogen to trichloride which may be precipitated on the wall of the vessel 8.
